<p>The present invention relates to an air-cooled grate block of a grate for the thermal treatment of waste, in which the grate blocks (1) are arranged so as to rest one on top of the other in a step-like manner. The block body (5) designed as a cast part has a top wall (10), forming a bearing surface (15), and a front wall (20), on which a foot (25) is integrally formed. A first cooling passage section (40) runs from a wall inlet (35), arranged on the underside (30) of thetopwall (10), through the top wall (10) and the front wall (20) to an outlet opening (45) arranged in the front wall (20). A cooling passage wall (55) which starts from an inlet opening (50) arranged adjacent to the foot (25) and to the front wall (20) and is at a distance from the front wall (20) and the top wall (10) forms a second cooling passage section (60) fluidically connected to the first cooling passage section (40) at the wall inlet (35). A grate which consists of the abovementioned grate blocks is likewise described.</p> |
